Spectral reflectance of metals
Description
Total reflectance of metals at 294 K (21 C), measured using an integrating sphere. Data are to be used as "reference values only" as actual values will depend on the state of the metal surface and its polish.
Usage
metals.mspct
Format
A reflector_mspct
object named metals.mspct
containing
a collection of reflector_spct
objects each with 47 rows and 2
variables.
The variables for each spectrum are as follows:
-
w.length
(nm) -
Rfr
(fraction)
These member objects contain metadata stored as R attributes. Accessors to
the metadata are available: what_measured()
, how_measured()
,
when_measured()
, and comment()
.
Note
Data extracted from a published report by OCR.
